The logic of the Christian Incarnation

As the Creator, God is the primary catagory of being. So, God can become a creature like a door can become luminous red. Our separation from God as sinners means that our efforts at salvation, or eternal life, is like groping back and forth along a very wide brick wall in total darkness, searching for an all-but-imperceptible door that leads through the wall to the other side. Many people decide that there is no door. When the door became luminous red, we could see it, and so be able to get through the wall, if we pry on the door with all that we are.
